背棘 (總數) : 15 - 17; 背的軟條 (總數) : 9 - 11; 臀棘: 5 - 7; 臀鰭軟條: 7 - 9. This species differs from its congeners in having a lower jaw longer than upper and mouth pointing upwards; has the shortest dorsal scale cover and the least scaled dorsal and anal fins among (together with A. tembe); with four abdominal bars (present in more than 80% of individuals as compared to 50% or less in all other species (Ref. 74689).
Body shape (shape guide): short and / or deep.
Body shape (shape guide): short and / or deep.
An opportunistic diurnal feeder, eating detritus and plant material, preying on small aquatic animals, including small fish. Very resistant to low temperatures. (Ref. 59043). Common in creeks, rivers, swamps and lakes (Ref. 74689). This species is an easy open spawner that lays its eggs on a stone or piece of wood (Ref. 12251). Both parents care for the eggs and fry (Ref. 12251). Consumed locally. Reported to reach 25.0 cm SL (Ref. 59043).

This species is an easy open spawner that lays its eggs on a stone or piece of wood. Both parents care for the eggs and fry (Ref. 12251). In Europe where it has invaded native drainages, spawns when temperature rises above 28-30°C. Forms pairs during spawning and both sexes are territorial. Females deposits eggs on exposed hard surfaces such as stones or wood. Both parent guard larvae and juveniles for 1-3 weeks (Ref. 59043).南美洲: 烏拉圭與 Rio Grande do Sul 巴西的海岸流域; 巴拉納河流域, 在阿根廷的巴拉納河的較下面的部位。
